  3. Multi-access in packet radio networks

    Arikan, E.

    1982-09-01

    A PRN (packet radio network) is a collection of geographically distributed, possibly mobile users where each user is capable of transmitting and receiving messages over a shared broadcast medium. In a PRN, messages are divided into packets, which may be fixed or variable in length, and each packet is transmitted through the network individually. Packets are assembled at their destinations to reconstruct the original messages. The data traffic in a PRN is characterized by specifying the average message arrival rates to the network for each o-d (origin-destination) pair. A set of o-d rates is called feasible if there exist network protocols under which the number of packets in the network still not delivered to their destinations remains finite with probability one. The capacity region of a PRN is defined to be the set of all feasible sets of o-d rates. In this thesis, PRNs are studied from the viewpoint of feasibility, i.e., we take an arbitrary set of message input rates as given and try to determine if it is feasible. Our main conclusion is that, unless P = NP, there exists no practical algorithm for characterizing the capacity region of a PRN, in the sense that the decision problem regarding the feasibility of a given set of o-d rates is NP-complete.

  6. Radio-parameter selection algorithm for receiver-directed packet-radio networks (SRNTN-73)

    NASA Astrophysics Data System (ADS)

    Escobar, Julio

    The Parameter Selection Algorithm for the SURAP 4 packet radio network and the basis for its design is described. A Semi-Markov model of the algorithm operation is presented. The algorithm adaptively adjusts three radio parameters: transmitter power, FEC coding rate, and channel bit rate. These parameters can increase the perceived signal-to-noise ratio on the channel and are treated as gain mechanisms. The algorithm must maintain robust radio links between nodes whenever possible, while minimizing interference with other network transmissions. We present one heuristic approach to balancing these two goals. This approach uses barely sufficient gain to maintain the packet error probability below an acceptable threshold value. A threshold probability of 0.1 was chosen. Bit error statistics provided by the sequential decoder and error feedback packets assist the process of determining the appropriate change of gain as noise levels vary. The algorithm can adapt at a fast rate, sometimes on the order of one packet time. It maintains acceptable packet error probability and can recover from estimation and decision errors. A Semi-Markov model can be used to compute the steady state packet error probability and packet transmission overhead due to noise. The model is general enough to include a stationary model of transceiver blocking probability, dynamic CDMA interference, and alternative algorithms based on similar operating principles. Although the model does not incorporate bit error statistic, a way is proposed to model the effect of these statistic without compromising the simplicity of the semi-Markov description.

  7. Discrete-event-dynamic-system-based approaches for scheduling transmissions in multihop packet radio networks

    NASA Astrophysics Data System (ADS)

    Cassandras, Christos G.

    In the classic transmission scheduling problem, the nodes of a packed radio network (PRN) broadcast fixed-length packets over a common resource (the channel). Packet transmissions are subject to interference constraints; for example, if a node is transmitting a packet, then all adjacent (neighboring) nodes must refrain from transmission. One then adopts a slotted time model where every slot is allocated to a set of nodes which can simultaneously transmit without conflict. Thus, a node generally belongs to one or more of these sets (called transmission sets). Our approach is based on viewing the transmission scheduling problem as a single server multiclass polling problem with simultaneous resource possession. Here, a class corresponds to a transmission set. The server corresponds to a channel operating with deterministic service times: a service time is equal to one time slot required for transmitting a packet. The scheduling problem is then equivalent to assigning the server (equivalently, each time slot) to a particular transmissions set. The simultaneous resource possession feature arises because the server is assigned to a transmission set, i.e. it can simultaneously provide service to packets from all nodes which belong to that set. The construction of the transmission set is dependent upon the topology and connectivity of the PRN and is equivalent to a graph partitioning problem. For our purposes, we assume M transmission sets have been specified. Finally, we allow for overlapping transmission sets, i.e. a node can belong to two or more difference transmission sets.

  8. Future directions in packet radio architectures and protocols

    NASA Astrophysics Data System (ADS)

    Shacham, Nachum; Westcott, Jil

    1987-01-01

    The technology of packet switching over multihop, multiple-access channels has evolved to the point at which its protocols can now support internetwork operation of medium-size networks whose nodes possess some degree of mobility. As regards the needs and challenges of the future operating environment, it is clear that these can be met only by enhancing the packet radio architecture and its protocols. Several enhancements that allow the organization of large, dynamic networks that can operate over multiple channels, adapt to varying conditions, and possess self-monitoring and self-control capabilities are discussed. As these areas are examined, the attendant issues and tradeoffs are discussed; in addition, some protocols and information regarding their performance are presented.

  9. Packet error probabilities in frequency-hopped spread spectrum packet radio networks. Markov frequency hopping patterns considered

    NASA Astrophysics Data System (ADS)

    Georgiopoulos, M.; Kazakos, P.

    1987-09-01

    We compute the packet error probability induced in a frequency-hopped spread spectrum packet radio network, which utilizes first order Markov frequency hopping patterns. The frequency spectrum is divided into q frequency bins and the packets are divided into M bytes each. Every user in the network sends each of the M bytes of his packet at a frequency bin, which is different from the frequency bin used by the previous byte, but equally likely to be any one of the remaining q-1 frequency bins (Markov frequency hopping patterns). Furthermore, different users in the network utilize statistically independent frequency hopping patterns. Provided that, K users have simultaneously transmitted their packets on the channel, and a receiver has locked on to one of these K packets, we present a method for the computation of P sub e (K) (i.e. the probability that this packet is incorrectly decoded). Furthermore, we present numerical results (i.e. P sub e (K) versus K) for various values of the multiple access interference K, when Reed Solomon (RS) codes are used for the encoding of packets. Finally, some useful comparisons, with the packet error probability induced, if we assume that the byte errors are independent, are made; based on these comparisons, we can easily evaluate the performance of our spread spectrum system.

  10. Wide-band packet radio for multipath environments

    NASA Astrophysics Data System (ADS)

    Fischer, Jeffrey H.; Cafarella, John H.; Bouman, Charles A.; Flynn, Gerard T.; Dolat, Victor S.

    1988-05-01

    A direct-sequence spread-spectrum packet radio is described that has versatile signal-processing and local-control capabilities designed to support the functions required of a robust mobile communications network. Noteworthy capabilities include eleven selectable data rates with accurate range measurements in a fading multipath channel. The radio uses a hybrid analog/digital signal processor and nonrepeating spreading codes for suppression of intersymbol interference and jamming. It incorporates two sets of monolithic surface-acoustic-wave convolvers as programmable matched filters with time-bandwidth products of 64 and 2000. The analog matched filters are coupled with binary postprocessing for the functions of detection, RAKE demodulation, and ranging measurements over a wide multipath spread. The data rate can be varied in response to channel conditions from 1.45 Mb/s down to 44 b/s with an almost ideal tradeoff in signal-processing gain from 18 dB up to 61 dB prior to multipath combining.

  11. Synthesis of optimum receiver and processor for signal packet of radio pulses

    NASA Astrophysics Data System (ADS)

    Ryabtsov, A. L.

    1985-03-01

    A quasi-coherent optimum receiver and processor for a useful signal packet of radio pulses appearing in an additive mixture with a stationary normal white noise is synthesized in accordance with the Markov theory of nonlinear filtration. In addition to a period estimator, multipliers, a differentiator, and a summator, the structure of this device includes a shaper of unit-amplitude video pulse packets, a fine-tunable carrier-frequency oscillator, and a (O, pi) phase keyer. The estimated error of period parameter filtration indicates that a packet of L radio pulses has a signal to noise ratio L times higher than a single pulse. In the extreme case of zero filtration error and a payoff of using pulse packets (M approaches the square root of L) the a-posteriori dispersion of the filtered period parameter is the square root of L times smaller in a packet than in a single radio pulse.

  12. Packet error probabilities in direct sequence spread spectrum packet radio networks with BCH codes

    NASA Astrophysics Data System (ADS)

    Georgiopoulos, Michael

    The author computes an upper bound on the packet error probability induced in direct-sequence spread-spectrum networks, when BCH codes are used for the encoding of the packets. The bound, which is introduced here, is valid independently of whether signals arrive with equal or unequal powers at the receiver site. Furthermore, it has a simple form and is easy to compute. In addition, it is valid for other classes of forward error correction codes (e.g., convolutional codes). However, numerical results are presented for BCH codes only.

    1994-01-01

    An amateur packet radio system operating in the very high frequency (VHF) range has been implemented in the Transport Systems Research Vehicle at the NASA Langley Research Center to provide an economical, bidirectional, real-time, ground-to-air data link. The packet system has been used to support flight research involving air traffic control (ATC), differential global positioning systems (DGPS), and windshear terminal doppler weather radar (TDWR). A data maximum rate of 2400 baud was used. Operational reliability of the packet system has been very good. Also, its versatility permits numerous specific configurations. These features, plus its low cost, have rendered it very satisfactory for support of data link flight experiments that do not require high data transfer rates.

  15. Non-intrusive Packet-Layer Model for Monitoring Video Quality of IPTV Services

    NASA Astrophysics Data System (ADS)

    Yamagishi, Kazuhisa; Hayashi, Takanori

    Developing a non-intrusive packet-layer model is required to passively monitor the quality of experience (QoE) during service. We propose a packet-layer model that can be used to estimate the video quality of IPTV using quality parameters derived from transmitted packet headers. The computational load of the model is lighter than that of the model that takes video signals and/or video-related bitstream information such as motion vectors as input. This model is applicable even if the transmitted bitstream information is encrypted because it uses transmitted packet headers rather than bitstream information. For developing the model, we conducted three extensive subjective quality assessments for different encoders and decoders (codecs), and video content. Then, we modeled the subjective video quality assessment characteristics based on objective features affected by coding and packet loss. Finally, we verified the model's validity by applying our model to unknown data sets different from training data sets used above.

  16. Analysis of frequency-hopped packet radio networks with random signal levels. Part 1: Error-only decoding

    NASA Astrophysics Data System (ADS)

    Mohamed, Khairi Ashour; Pap, Laszlo

    1994-05-01

    This paper is concerned with the performance analysis of frequency-hopped packet radio networks with random signal levels. We assume that a hit from an interfering packet necessitates a symbol error if and only if it brings on enough energy that exceeds the energy received from the wanted signal. The interdependence between symbol errors of an arbitrary packet is taken into consideration through the joint probability generating function of the so-called effective multiple access interference. Slotted networks, with both random and deterministic hopping patterns, are considered in the case of both synchronous and asynchronous hopping. A general closed-form expression is given for packet capture probability, in the case of Reed-Solomon error only decoding. After introducing a general description method, the following examples are worked out in details: (1) networks with random spatial distribution of stations (a model for mobile packet radio networks); (2) networks operating in slow fading channels; (3) networks with different power levels which are chosen randomly according to either discrete or continuous probability distribution (created captures).

  17. Experimental evaluation of the impact of packet capturing tools for web services.

    2011-10-01

    Network measurement is a discipline that provides the techniques to collect data that are fundamental to many branches of computer science. While many capturing tools and comparisons have made available in the literature and elsewhere, the impact of these packet capturing tools on existing processes have not been thoroughly studied. While not a concern for collection methods in which dedicated servers are used, many usage scenarios of packet capturing now requires the packet capturing tool to run concurrently with operational processes. In this work we perform experimental evaluations of the performance impact that packet capturing process have on web-based services; in particular, we observe the impact on web servers. We find that packet capturing processes indeed impact the performance of web servers, but on a multi-core system the impact varies depending on whether the packet capturing and web hosting processes are co-located or not. In addition, the architecture and behavior of the web server and process scheduling is coupled with the behavior of the packet capturing process, which in turn also affect the web server's performance.

    2007-11-01

    The unprecedented proliferation of packet-based services such as numerical television, video on demand, is pushing Metropolitan Area Networks (MANs) providers to reconsider their network infrastructures. The existing circuit-based networks are becoming inefficient and costly in supporting the new requirements in terms of quality of service and bandwidth of sporadic packet-based traffic. To solve this problem, new MAN infrastructures are needed. Many propositions of new network solutions were made during the last decade in order to respond to the aforementioned issues, such as Next Generation SONET/SDH, Resilient Packet Ring (RPR). Among others, the optical networking technology appears as a technology of choice for the next generation MANs. The main benefit of optical technology can be resumed in the following terms: huge transmission capacity, high reliability, and high availability. This paper is devoted to provide an overview of the MAN infrastructure, and particularly to its evolution towards optical packet switching (OPS) networks, during the last decades. It also highlights performance issues in optical networking in metro area in terms of optical packet format, medium access control (MAC) protocol and quality of service (QoS), as well as traffic engineering issues. We first begin with a brief state-of-the-art and perspective on optical networking in metropolitan area. Next, we provide the necessary arguments for an answer to the problem of the choice of packet format (fixed format versus variable format) to be adopted in future metropolitan optical packet switching networks. Comparison of different optical packet formats at the electronic to optical (E/O) interface is carried out, followed by the analysis of the impact of optical packet format choices on overall network performance. Then, we explore the performance issue at MAC layer and discuss improvement mechanisms for MAC protocol. Here, fairness and bandwidth utilization issues are specifically

  20. Enhanced Class-of-Service Oriented Packet Scheduling Scheme for EPON Access Networks

    NASA Astrophysics Data System (ADS)

    Han, Intark; Park, Hong-Shik; Han, Man-Soo

    A fast class-of-service oriented packet scheduling (FCOPS) has a service fairness problem since a credit pool for a service class is initialized at the beginning of a transmission cycle whose starting moment is fixed at a specific ONU. To remedy the service unfairness of FCOPS, we suggest an enhanced class-of-service oriented packet scheduling (ECOPS) that uses a new initialization cycle whose starting moment is fairly distributed to each ONU. Also, ECOPS generates a colorless grant to utilize the resource wastage, when traffic is light and the total sum of grants of an ONU is less than a minimum size. Using simulation, we validate ECOPS as superior to FCOPS in the mean delay and the service fairness.

  1. Parametric Packet-Layer Model for Evaluation Audio Quality in Multimedia Streaming Services

    NASA Astrophysics Data System (ADS)

    Egi, Noritsugu; Hayashi, Takanori; Takahashi, Akira

    We propose a parametric packet-layer model for monitoring audio quality in multimedia streaming services such as Internet protocol television (IPTV). This model estimates audio quality of experience (QoE) on the basis of quality degradation due to coding and packet loss of an audio sequence. The input parameters of this model are audio bit rate, sampling rate, frame length, packet-loss frequency, and average burst length. Audio bit rate, packet-loss frequency, and average burst length are calculated from header information in received IP packets. For sampling rate, frame length, and audio codec type, the values or the names used in monitored services are input into this model directly. We performed a subjective listening test to examine the relationships between these input parameters and perceived audio quality. The codec used in this test was the Advanced Audio Codec-Low Complexity (AAC-LC), which is one of the international standards for audio coding. On the basis of the test results, we developed an audio quality evaluation model. The verification results indicate that audio quality estimated by the proposed model has a high correlation with perceived audio quality.

  2. A novel timestamp based adaptive clock method for circuit emulation service over packet network

    NASA Astrophysics Data System (ADS)

    Dai, Jin-you; Yu, Shao-hua

    2007-11-01

    It is necessary to transport TDM (time division multiplexing) over packet network such as IP and Ethernet, and synchronization is a problem when carrying TDM over the packet network. Clock methods for TDM over packet network are introduced. A new adaptive clock method is presented. The method is a kind of timestamp based adaptive method, but no timestamp needs transporting over packet network. By using the local oscillator and a counter, the timestamp information (local timestamp) related to the service clock of the remote PE (provide edge) and the near PE can be attained. By using D-EWMA filter algorithm, the noise caused by packet network can be filtered and the useful timestamp can be extracted out. With the timestamp and a voltage-controlled oscillator, clock frequency of near PE can be adjusted the same as clock frequency of the remote PE. A kind of simulation device is designed and a test network topology is set up to test and verify the method. The experiment result shows that synthetical performance of the new method is better than ordinary buffer based method and ordinary timestamp based method.

  12. Field Experiments on Real-Time 1-Gbps High-Speed Packet Transmission in MIMO-OFDM Broadband Packet Radio Access

    NASA Astrophysics Data System (ADS)

    Taoka, Hidekazu; Higuchi, Kenichi; Sawahashi, Mamoru

    This paper presents experimental results in real propagation channel environments of real-time 1-Gbps packet transmission using antenna-dependent adaptive modulation and channel coding (AMC) with 4-by-4 MIMO multiplexing in the downlink Orthogonal Frequency Division Multiplexing (OFDM) radio access. In the experiment, Maximum Likelihood Detection employing QR decomposition and the M-algorithm (QRM-MLD) with adaptive selection of the surviving symbol replica candidates (ASESS) is employed to achieve such a high data rate at a lower received signal-to-interference plus background noise power ratio (SINR). The field experiments, which are conducted at the average moving speed of 30km/h, show that real-time packet transmission of greater than 1Gbps in a 100-MHz channel bandwidth (i.e., 10bits/second/Hz) is achieved at the average received SINR of approximately 13.5dB using 16QAM modulation and turbo coding with the coding rate of 8/9. Furthermore, we show that the measured throughput of greater than 1Gbps is achieved at the probability of approximately 98% in a measurement course, where the maximum distance from the cell site was approximately 300m with the respective transmitter and receiver antenna separation of 1.5m and 40cm with the total transmission power of 10W. The results also clarify that the minimum required receiver antenna spacing is approximately 10cm (1.5 carrier wave length) to suppress the loss in the required received SINR at 1-Gbps throughput to within 1dB compared to that assuming the fading correlation between antennas of zero both under non-line-of-sight (NLOS) and line-of-sight (LOS) conditions.

  13. Phase Coupling in Langmuir Wave Packets: Evidence for Four Wave Interactions in Solar Type III Radio Bursts

    NASA Technical Reports Server (NTRS)

    Thejappa, G.; MacDowall, R. J.; Bergamo, M.

    2012-01-01

    The four wave interaction process, known as the oscillating two stream instability (OTSI) is considered as one of the mechanisms responsible for stabilizing the electron beams associated with solar type III radio bursts. It has been reported that (1) an intense localized Langmuir wave packet associated with a type III burst contains the spectral characteristics of the OTSI: (a) a resonant peak at the local electron plasma frequency, f(sub pe), (b) a Stokes peak at a frequency slightly lower than f(sub pe), (c) anti-Stokes peak at a frequency slightly higher than f(sub pe), and (d) a low frequency enhancement below a few hundred Hz, (2) the frequencies and wave numbers of these spectral components satisfy the resonance conditions of the OTSI, and (3) the peak intensity of the wave packet is well above the thresholds for the OTSI as well as spatial collapse of envelope solitons. Here, for the first time, applying the trispectral analysis on this wave packet, we show that the tricoherence, which measures the degree of coherent four-wave coupling amongst the observed spectral components exhibits a peak. This provides an additional evidence for the OTSI and related spatial collapse of Langmuir envelope solitons in type III burst sources.

    Public radio can survive cutbacks in federal subsidies, but only if these funds are reduced no more rapidly than public radio can replace them with newly-generated audience-sensitive revenues (listener support and underwriting). A model developed in this analysis suggests a three-to-five year "glide path" to zero federal support. Public radio has…

  15. Enhancing In-Flight Transoceanic Communications Using Swift-64 Packet Mode Service

    NASA Technical Reports Server (NTRS)

    Slywczak, Richard A.

    2004-01-01

    Current aeronautical communications can be divided into two segments. The first provides state of the art, packet switched technology to the cabin passengers so that they have access to e-mail and web services. The second provides basic circuit switch communication technology to the cockpit, which does not use bandwidth as efficiently as packet switching nor promotes resource sharing. This paper explores the research efforts currently being conducted by the NASA/Glenn Research Center (GRC) for transoceanic communications. The goal is to bring packet mode services to both the cabin and the cockpit of the aircraft and be able to attain benefits by sharing the data link with cabin services. First, this paper will outline the goals of the program and detail the benefits and issues related to this research. We will explain our current laboratory setup and show an architecture implemented in the testbed. Finally, we will present a work plan that will show the progression of research over the next year. This plan will describe a complete cycle from conceptual design and laboratory implementation to the final flight testing.

  6. Providing packet-level quality of services in multihop wireless networks

    NASA Astrophysics Data System (ADS)

    Cheng, Jerry; Zhong, Gary; Luo, Haiyun; Lu, Songwu

    2001-07-01

    Providing packet-level quality of service (QoS) is critical to support both rate-sensitive and delay-sensitive applications in the bandwidth-constrained, shared-channel, multihop wireless networks. This problem is challenging due to the unique issues such as location-dependent contention, inherent conflict between ensuring fairness and maximizing channel utilization, and the distributed nature of packet scheduling in such networks. In order to address these issues, we have taken a new self-organizing approach to QoS solutions for such networks. In this approach, local decision makers self-organize themselves and coordinate among one another, and collectively achieve the desired global property. Some features of our approach include fully localized design, coordination among local decision makers, intentional and optimized information propagation, scaling property and achievable global property. Two key contributions of this work are: (a) a model-referenced self-organizing design methodology for multihop wireless networks; and (b) a table-driven approach and a backoff-based approach to distributed packet scheduling that provides QoS performance bounds in terms of fairness, throughput and delay, maximizes channel spatial reuse, and arbitrates the conflict between fairness and maximal channel utilization. oth proposed designs work within the CSMA/CA MAC framework. We also compare the performance of these two approaches through simulations. Our extensive simulation results have confirmed the effectiveness of the proposed design.

  2. Performance evaluation of multi-access strategies for an integrated voice/data CDMA packet radio network

    NASA Astrophysics Data System (ADS)

    Geraniotis, Evaggelos; Soroushnejad, Mohsen

    1990-11-01

    The problem of voice/data integration in a random-access radio network employing the ALOHA protocol in conjunction with retransmission control is investigated. Channel-access control strategies are introduced that take advantage of the capability of the code-division multiple-access (CDMA) channel to accommodate several voice calls simultaneously, while the data users contend for the remaining (if any) multiple-access capability of that channel. The retransmission probabilities of the backlogged data users are updated based on estimates of data backlog and number of established voice calls, which are obtained from the side information about the state of channel activities. A two-dimensional Markovian model is developed for the voice and data traffic. Based on this model, the voice-call blocking probability, the throughput of both traffic types, and the delay of the data packets are evaluated and the tradeoffs between the parameters of different traffic types are quantified. It is observed that by taking advantage of the multiple-access capability of the CDMA channel in the control of data traffic, we may achieve movable-boundary channel access in the code domain.

    2012-01-01

    NASAs Space Communication and Navigation(SCaN) Testbed was launched to the International Space Station in 2012. The objective is to promote new software defined radio technologies and associated software application reuse, enabled by this first flight of NASAs Space Telecommunications Radio System(STRS) architecture standard. Pre-launch testing with the testbeds software defined radios was performed as part of system integration. Radio services for the JPL SDR were developed during system integration to allow the waveform application to operate properly in the space environment, especially considering thermal effects. These services include receiver gain control, frequency offset, IQ modulator balance, and transmit level control. Development, integration, and environmental testing of the radio services will be described. The added software allows the waveform application to operate properly in the space environment, and can be reused by future experimenters testing different waveform applications. Integrating such services with the platform provided STRS operating environment will attract more users, and these services are candidates for interface standardization via STRS.

  15. Reliability aspects of the future hybrid optical network and quality of service issues for real time and packet traffic

    NASA Astrophysics Data System (ADS)

    Marciniak, Marian

    2004-09-01

    While Internet traffic increases dramatically and now it exceeds the almost stable voice traffic, new efficient solutions for network architecture are sought. One of the main problems to be resolved is the basic concept of the future network performance. While actual networks are based on 'circuit switching' connection networks with IP packets forwarded given the network offers some free resources, a number of researchers foresee the future network as a 'packet switched' connectionless network which would support also the traditional real time services with phone calls as the most representative example. This is driven by the growing use of voice over IP services. Unfortunately, the Quality of Service is actually not sufficient for wide acceptance of that technique. In fact, Internet is based on the 'best-effort' principle in what it fudamentally differs from circuit-switched network which has been developed uniquely to provide excellent voice quality during last century. Moreover, the reliability of the network is a crucial factor in emergency communications, what has recently became a subject of intense activity at national and international scale. As a consequence, the idea of dropping the converged network with voice-over-IP concept is hard to accept for a great majority and those expressing it are usually looked as strange or even dangerous individuals. Nevertheless, those fundamental difficulties become obvious for a growing number of people who approach the future network evolution more fundamentally, and try to trace reasonable and economic ways of the future network development. The author of this paper has extensively developed a concept of a "hybrid network" which consists of real-time subnetwork and packet network separated in the optical frequency domain that will be discussed in detail in this paper. This optimized network concept is intended to guarantee both reliability of the network and Quality of Service as well.

  17. Bit-to-bit error dependence in direct-sequence spread-spectrum multiple-access packet radio systems

    NASA Astrophysics Data System (ADS)

    Morrow, Robert K., Jr.

    1988-05-01

    Slotted direct-sequence spread-spectrum multiple-access (DS/SSMA) packet broadcasting systems with random signature sequences are analyzed within the framework of the lower three layers of the International Standards Organization Reference Model of Open Systems Interconnection. At the physical layer, we show that a widely-used Gaussian approximation (which we call the Standard Gaussian Approximation) for the probability of data bit error in a chip and phase asynchronous system is accurate only when there are a large number of simultaneous users on the channel; otherwise, this approximation can be optimistic by several orders of magnitude. For interfering signals with fixed delays and phases relative to the desired signal, however, the Standard Gaussian Approximation is quite accurate for any number of simultaneous users. To obtain a closer approximation to the probability of data bit error for an asynchronous system, we introduce the Improved Gaussian Approximation, which involves finding the distribution of the multiple-access interference variance over all possible delay and phase values and then taking a Gaussian approximation over the support of the distribution and averaging the results. To accurately analyze packet performance at the data link layer, we first use the theory of moment spaces to gain insight on the effect of bit-to-bit error dependence caused by the constant relative delays and (possibly) phases of the interfering signals over the duration of a desired packet.

  6. A Study of Quality of Service Communication for High-Speed Packet-Switching Computer Sub-Networks

    NASA Technical Reports Server (NTRS)

    Cui, Zhenqian

    1999-01-01

    In this thesis, we analyze various factors that affect quality of service (QoS) communication in high-speed, packet-switching sub-networks. We hypothesize that sub-network-wide bandwidth reservation and guaranteed CPU processing power at endpoint systems for handling data traffic are indispensable to achieving hard end-to-end quality of service. Different bandwidth reservation strategies, traffic characterization schemes, and scheduling algorithms affect the network resources and CPU usage as well as the extent that QoS can be achieved. In order to analyze those factors, we design and implement a communication layer. Our experimental analysis supports our research hypothesis. The Resource ReSerVation Protocol (RSVP) is designed to realize resource reservation. Our analysis of RSVP shows that using RSVP solely is insufficient to provide hard end-to-end quality of service in a high-speed sub-network. Analysis of the IEEE 802.lp protocol also supports the research hypothesis.

  3. An economic systems analysis of land mobile radio telephone services

    NASA Technical Reports Server (NTRS)

    Leroy, B. E.; Stevenson, S. M.

    1980-01-01

    This paper deals with the economic interaction of the terrestrial and satellite land-mobile radio service systems. The cellular, trunked and satellite land-mobile systems are described. Parametric equations are formulated to allow examination of necessary user thresholds and growth rates as functions of system costs. Conversely, first order allowable systems costs are found as a function of user thresholds and growth rates. Transitions between satellite and terrestrial service systems are examined. User growth rate density (user/year/km squared) is shown to be a key parameter in the analysis of systems compatibility. The concept of system design matching the price demand curves is introduced and examples are given. The role of satellite systems is critically examined and the economic conditions necessary for the introduction of satellite service are identified.

    A global rain rate statistic model is used to link microwave propagation statistics to measurable rain statistics in order to develop international telecommunication site criteria for radio relay and communication satellite services that minimize interference between receivers and transmitters. This rain coordination procedure utilizes a rain storm cell size, a statistical description of the rainfall rate within the cell valid for most of the earth's surface, approximations between Raleigh scatter and constancy of precipitation with altitude, and an analytic relation between radar reflectivity and rain rate.

  8. Automation of servicibility of radio-relay station equipment

    NASA Astrophysics Data System (ADS)

    Uryev, A. G.; Mishkin, Y. I.; Itkis, G. Y.

    1985-03-01

    Automation of the serviceability of radio relay station equipment must ensure central gathering and primary processing of reliable instrument reading with subsequent display on the control panel, detection and recording of failures soon enough, advance enough warning based on analysis of detertioration symptoms, and correct remote measurement of equipment performance parameters. Such an inspection will minimize transmission losses while reducing nonproductive time and labor spent on documentation and measurement. A multichannel automated inspection system for this purpose should operate by a parallel rather than sequential procedure. Digital data processing is more expedient in this case than analog method and, therefore, analog to digital converters are required. Spepcial normal, above limit and below limit test signals provide means of self-inspection, to which must be added adequate interference immunization, stabilization, and standby power supply. Use of a microcomputer permits overall refinement and expansion of the inspection system while it minimizes though not completely eliminates dependence on subjective judgment.

    NASA Technical Reports Server (NTRS)

    Ferzali, Wassim; Zacharakis, Vassilis; Upadhyay, Triveni; Weed, Dennis; Burke, Gregory

    1995-01-01

    The ICAO Aeronautical Mobile Communications Panel (AMCP) completed the drafting of the Aeronautical Mobile Satellite Service (AMSS) Standards and Recommended Practices (SARP's) and the associated Guidance Material and submitted these documents to ICAO Air Navigation Commission (ANC) for ratification in May 1994. This effort, encompassed an extensive, multi-national SARP's validation. As part of this activity, the US Federal Aviation Administration (FAA) sponsored an effort to validate the SARP's via computer simulation. This paper provides a description of this effort. Specifically, it describes: (1) the approach selected for the creation of a high-fidelity AMSS computer model; (2) the test traffic generation scenarios; and (3) the resultant AMSS performance assessment. More recently, the AMSS computer model was also used to provide AMSS performance statistics in support of the RTCA standardization activities. This paper describes this effort as well.

  2. A Distributed Datacube Analysis Service for Radio Telescopes

    NASA Astrophysics Data System (ADS)

    Mahadevan, V.; Rosolowsky, E.

    2011-07-01

    Current- and next-generation radio telescopes are poised to produce data at an unprecedented rate. We are developing the cyberinfrastructure to enable distributed processing and storage of FITS data cubes from these telescopes. In this contribution, we will present the data storage and network infrastructure that enables efficient searching, extraction and transfer of FITS datacubes. The infrastructure combines the iRODS distributed data management with a custom spatially-enabled PostgreSQL database. The data management system ingests FITS cubes, automatically populating the metadata database using FITS header data. Queries to the metadata service return matching records using VOTable format. The iRODS system allows for a distributed network of fileservers to store large data sets redundantly with a minimum of upkeep. Transfers between iRODS data sites use parallel I/O streams for maximum speed. Files are staged to the optimal host for download by an end user. The service can automatically extract subregions of individual or adjacent cubes registered to user-defined astrometric grids using the Montage package. The data system can query multiple surveys and return spatially registered data cubes to the user. Future development will allow the data system to utilize distributed processing environment to analyze datasets, returning only the calculation results to the end user. This cyberinfrastructure project combines many existing, open-source packages into a single deployment of a data system. The codebase can also function on two-dimensional images. The project is funded by CANARIE under the Network-Enabled Platforms 2 program.

    The author assesses wide-area networking end-user needs as they evolve into the 1990s. He then turns to the network operator environment, both public and private, by examining service evolution trends. The author concludes with an assessment of how packet switching services and technologies are evolving to continue to match the identified market requirements, with specific emphasis on Northern Telecom's DPN Data Networking System. Key evolving DPN capabilities include the introduction of the high-end DPN100 30-kb/s switch, a variety of access options including ISDN (integrated services digital network) packet mode services, higher throughput virtual circuits, megabit trunking for improved network throughput and end-user transit delay, and SNA session switching, the latter being an example of adding value to packet networking through communication processing.

    Robertson, Perry J.; Hamlet, Jason R.; Pierson, Lyndon G.; Olsberg, Ronald R.; Chun, Guy D.

    2013-08-20

    A technique for distributed packet processing includes sequentially passing packets associated with packet flows between a plurality of processing engines along a flow through data bus linking the plurality of processing engines in series. At least one packet within a given packet flow is marked by a given processing engine to signify by the given processing engine to the other processing engines that the given processing engine has claimed the given packet flow for processing. A processing function is applied to each of the packet flows within the processing engines and the processed packets are output on a time-shared, arbitered data bus coupled to the plurality of processing engines.

  13. Analysis of QoS Requirements for e-Health Services and Mapping to Evolved Packet System QoS Classes

    PubMed Central

    Skorin-Kapov, Lea; Matijasevic, Maja

    2010-01-01

    E-Health services comprise a broad range of healthcare services delivered by using information and communication technology. In order to support existing as well as emerging e-Health services over converged next generation network (NGN) architectures, there is a need for network QoS control mechanisms that meet the often stringent requirements of such services. In this paper, we evaluate the QoS support for e-Health services in the context of the Evolved Packet System (EPS), specified by the Third Generation Partnership Project (3GPP) as a multi-access all-IP NGN. We classify heterogeneous e-Health services based on context and network QoS requirements and propose a mapping to existing 3GPP QoS Class Identifiers (QCIs) that serve as a basis for the class-based QoS concept of the EPS. The proposed mapping aims to provide network operators with guidelines for meeting heterogeneous e-Health service requirements. As an example, we present the QoS requirements for a prototype e-Health service supporting tele-consultation between a patient and a doctor and illustrate the use of the proposed mapping to QCIs in standardized QoS control procedures.

  18. Estimating the size of a radio quiet zone for the radio astronomy service

    NASA Astrophysics Data System (ADS)

    Peng, Bo; Han, Wenjun

    2009-12-01

    The size of a radio quiet zone (RQZ) is largely determined by transmission losses of interfering signals, which can be divided into free space loss and diffraction loss. The free space loss is dominant. The diffraction loss presented in this paper is described as unified smooth spherical and knife edge diffractions, which is a function of minimum path clearance. We present a complete method to calculate the minimum path clearance. The cumulative distribution of the lapse rate of refractivity ( g n ), between the earth surface and 1 km above, is studied by using Chinese radio climate data. Because the size of an RQZ is proportional to g n , the cumulative distribution of g n can be used as an approximation for the size of the RQZ. When interference originates from mobile communication or television transmissions at a frequency of 408 MHz, and overline {g_n } is 40 N/km, where the refractivity N=left( {n-1} right) × 10^6, the size of the RQZ would be 180 km for a mobile source or 210 km for a television source, with a probability in the range of 15-100% in different months and for different stations. When speaking of the size of an RQZ, the radius in the case of a circular zone is implied. It results that a size of an RQZ is mainly influenced by transmission loss rather than effective radiated power. In the case where the distance between an interfering source and a radio astronomical observatory is about 100 km, at a frequency of 408 MHz, the allowable effective radiated power of the interfering source should be less than -30 dBW with a probability of about 85% for overline {g_n } equals 40 N/km, or -42 dBW with a probability less than 1 % for overline {g_n } equals 80 N/km.

  19. Reliable Location-Based Services from Radio Navigation Systems

    PubMed Central

    Qiu, Di; Boneh, Dan; Lo, Sherman; Enge, Per

    2010-01-01

    Loran is a radio-based navigation system originally designed for naval applications. We show that Loran-C’s high-power and high repeatable accuracy are fantastic for security applications. First, we show how to derive a precise location tag—with a sensitivity of about 20 meters—that is difficult to project to an exact location. A device can use our location tag to block or allow certain actions, without knowing its precise location. To ensure that our tag is reproducible we make use of fuzzy extractors, a mechanism originally designed for biometric authentication. We build a fuzzy extractor specifically designed for radio-type errors and give experimental evidence to show its effectiveness. Second, we show that our location tag is difficult to predict from a distance. For example, an observer cannot predict the location tag inside a guarded data center from a few hundreds of meters away. As an application, consider a location-aware disk drive that will only work inside the data center. An attacker who steals the device and is capable of spoofing Loran-C signals, still cannot make the device work since he does not know what location tag to spoof. We provide experimental data supporting our unpredictability claim. PMID:22163532

    Loran is a radio-based navigation system originally designed for naval applications. We show that Loran-C's high-power and high repeatable accuracy are fantastic for security applications. First, we show how to derive a precise location tag--with a sensitivity of about 20 meters--that is difficult to project to an exact location. A device can use our location tag to block or allow certain actions, without knowing its precise location. To ensure that our tag is reproducible we make use of fuzzy extractors, a mechanism originally designed for biometric authentication. We build a fuzzy extractor specifically designed for radio-type errors and give experimental evidence to show its effectiveness. Second, we show that our location tag is difficult to predict from a distance. For example, an observer cannot predict the location tag inside a guarded data center from a few hundreds of meters away. As an application, consider a location-aware disk drive that will only work inside the data center. An attacker who steals the device and is capable of spoofing Loran-C signals, still cannot make the device work since he does not know what location tag to spoof. We provide experimental data supporting our unpredictability claim. PMID:22163532

  3. Maritime radio-medical services: the Singapore General Hospital experience.

    2002-07-01

    Medical care for the sick and injured on a variety of sea-faring vessels throughout the world represents a challenging area of medical care. The scope is extremely broad and unique in terms of the problems encountered at sea, logistical difficulties in assessment and treatment of patients, as well as the provision of definitive care. The problems of sparse resources availability, great distances, isolation, communications, accessibility, and weather are also very real. In Singapore, radio-medical advice was first coordinated by the Port Health Authority. In 1980, the accident and emergency department at Singapore General Hospital took over this responsibility. This report analyzes 2,320 calls received over a period of 21 years (January 1980 to December 2000). It highlights the common consultations, modes of communications, treatment and management prescribed, training requirements, as well as the challenges for the future. PMID:12098185

  4. Effect of the 24 September 2011 solar radio burst on precise point positioning service

    NASA Astrophysics Data System (ADS)

    Sreeja, V.; Aquino, M.; Jong, Kees; Visser, Hans

    2014-03-01

    An intense solar radio burst occurred on 24 September 2011, which affected the tracking of Global Navigation Satellite Systems' (GNSS) signals by receivers located in the sunlit hemisphere of the Earth. This manuscript presents for the first time the impacts of this radio burst on the availability of Fugro's real-time precise point positioning service for GNSS receivers and on the quality of the L band data link used to broadcast this service. During the peak of the radio burst (12:50-13:20 UT), a reduction in the L band signal-to-noise ratio (SNR) is observed. For some receiver locations, a reset in the position filter is observed, which can be either due to the reduction in the L band SNR or the reduction in the number of tracked GNSS satellites. This reset in the position filter is accompanied by degradation in the positioning accuracy, which is also discussed herein.

  9. A Study of Quality of Service Communication for High-Speed Packet-Switching Computer Sub-Networks

    NASA Technical Reports Server (NTRS)

    Cui, Zhenqian

    1999-01-01

    With the development of high-speed networking technology, computer networks, including local-area networks (LANs), wide-area networks (WANs) and the Internet, are extending their traditional roles of carrying computer data. They are being used for Internet telephony, multimedia applications such as conferencing and video on demand, distributed simulations, and other real-time applications. LANs are even used for distributed real-time process control and computing as a cost-effective approach. Differing from traditional data transfer, these new classes of high-speed network applications (video, audio, real-time process control, and others) are delay sensitive. The usefulness of data depends not only on the correctness of received data, but also the time that data are received. In other words, these new classes of applications require networks to provide guaranteed services or quality of service (QoS). Quality of service can be defined by a set of parameters and reflects a user's expectation about the underlying network's behavior. Traditionally, distinct services are provided by different kinds of networks. Voice services are provided by telephone networks, video services are provided by cable networks, and data transfer services are provided by computer networks. A single network providing different services is called an integrated-services network.

    The economic interaction of the terrestrial and satellite systems is considered. Parametric equations are formulated to allow examination of necessary user thresholds and growth rates as a function of system costs. Conversely, first order allowable systems costs are found as a function of user thresholds and growth rates. Transitions between satellite and terrestrial service systems are examined. User growth rate density (user/year/sq km) is shown to be a key parameter in the analysis of systems compatibility. The concept of system design matching the price/demand curves is introduced and examples are given. The role of satellite systems is critically examined and the economic conditions necessary for the introduction of satellite service are identified.

  13. Television Compression Algorithms And Transmission On Packet Networks

    NASA Astrophysics Data System (ADS)

    Brainard, R. C.; Othmer, J. H.

    1988-10-01

    Wide-band packet transmission is a subject of strong current interest. The transmission of compressed TV signals over such networks is possible with any quality level. There are some specific advantages in using packet networks for TV transmission. Namely, any fixed data rate can be chosen, or a variable data rate can be utilized. However, on the negative side packet loss must be considered and differential delay in packet arrival must be compensated. The possibility of packet loss has a strong influence on compression algorithm choice. Differential delay of packet arrival is a new problem in codec design. Some issues relevant to mutual design of the transmission networks and compression algorithms will be presented. An assumption is that the packet network will maintain packet sequence integrity. For variable-rate transmission, a reasonable definition of peak data rate is necessary. Rate constraints may be necessary to encourage instituting a variable-rate service on the networks. The charging algorithm for network use will have an effect on selection of compression algorithm. Some values of and procedures for implementing packet priorities are discussed. Packet length has only a second-order effect on packet-TV considerations. Some examples of a range of codecs for differing data rates and picture quality are given. These serve to illustrate sensitivities to the various characteristics of packet networks. Perhaps more important, we talk about what we do not know about the design of such systems.

  17. A Spectrum Access Based on Quality of Service (QoS) in Cognitive Radio Networks

    PubMed Central

    Zhai, Linbo; Wang, Hua; Gao, Chuangen

    2016-01-01

    The quality of service (QoS) is important issue for cognitive radio networks. In the cognitive radio system, the licensed users, also called primary users (PUs), are authorized to utilize the wireless spectrum, while unlicensed users, also called secondary users (SUs), are not authorized to use the wireless spectrum. SUs access the wireless spectrum opportunistically when the spectrum is idle. While SUs use an idle channel, the instance that PUs come back makes SUs terminate their communications and leave the current channel. Therefore, quality of service (QoS) is difficult to be ensured for SUs. In this paper, we first propose an analysis model to obtain QoS for cognitive radio networks such as blocking probability, completed traffic and termination probability of SUs. When the primary users use the channels frequently, QoS of SUs is difficult to be ensured, especially the termination probability. Then, we propose a channel reservation scheme to improve QoS of SUs. The scheme makes the terminated SUs move to the reserved channels and keep on communications. Simulation results show that our scheme can improve QoS of SUs especially the termination probability with a little cost of blocking probability in dynamic environment. PMID:27171196

  8. Dense wavelength division multiplexing photonic transport for radio frequency and microwave wireless services

    NASA Astrophysics Data System (ADS)

    2004-10-01

    The expected increase in space and terrestrial services that include two-way fixed, SATCOM, CATV and mobile wireless services require expanding the system capacity. This expansion has created an opportunity for the utilization of the demonstrated photonic transport systems in wireless networks. System demonstrations and architectural developments have been proposed for distribution of communication services over fiber. Termed Fiber Radio and Hybrid Fiber Wireless, these systems offer the potential to improve services and reduce base station costs through increased bandwidth and ease of installation. We have developed and demonstrated DWDM broadband photonic transport systems able to meet the requirements for IS-95 Personal Communications Services operating at 1.9 GHz and Broadband Wireless Internet operating over the band of 2.5 to 2.7 GHz. Each DWDM channel operates from 1 to 3 GHz transporting services up to 80 Km. Solutions are being sought for low cost transmitters to meet DWDM SATCOM system requirements include extending the transmission distance to over 100 Km with a bandwidth that exceeds multiple octaves. These new requirements put high performance demands on the optical components. We have developed high performance transmitters based on electro-absorption modulated lasers (EML) that can meet SATCOM requirements. We have shown that the EML is capable of providing the required CNR of 32 dB for satellite transmission in the band of 950 to 2150 MHz over a 100 Km distance. In addition, we are investigating a new modulation technique, Microwave Photonic Vector Modulation (MPVM), which has the potential for wideband transmission in DWDM systems.

  9. Experimental demonstration of multi-dimensional resources integration for service provisioning in cloud radio over fiber network

    Cloud radio access network (C-RAN) becomes a promising scenario to accommodate high-performance services with ubiquitous user coverage and real-time cloud computing in 5G area. However, the radio network, optical network and processing unit cloud have been decoupled from each other, so that their resources are controlled independently. Traditional architecture cannot implement the resource optimization and scheduling for the high-level service guarantee due to the communication obstacle among them with the growing number of mobile internet users. In this paper, we report a study on multi-dimensional resources integration (MDRI) for service provisioning in cloud radio over fiber network (C-RoFN). A resources integrated provisioning (RIP) scheme using an auxiliary graph is introduced based on the proposed architecture. The MDRI can enhance the responsiveness to dynamic end-to-end user demands and globally optimize radio frequency, optical network and processing resources effectively to maximize radio coverage. The feasibility of the proposed architecture is experimentally verified on OpenFlow-based enhanced SDN testbed. The performance of RIP scheme under heavy traffic load scenario is also quantitatively evaluated to demonstrate the efficiency of the proposal based on MDRI architecture in terms of resource utilization, path blocking probability, network cost and path provisioning latency, compared with other provisioning schemes.

  12. Wireless Avionics Packet to Support Fault Tolerance for Flight Applications

    In this protocol and packet format, data traffic is monitored by all network interfaces to determine the health of transmitter and subsystems. When failures are detected, the network inter face applies its recover y policies to provide continued service despite the presence of faults. The protocol, packet format, and inter face are independent of the data link technology used. The current demonstration system supports both commercial off-the-shelf wireless connections and wired Ethernet connections. Other technologies such as 1553 or serial data links can be used for the network backbone. The Wireless Avionics packet is divided into three parts: a header, a data payload, and a checksum. The header has the following components: magic number, version, quality of service, time to live, sending transceiver, function code, payload length, source Application Data Interface (ADI) address, destination ADI address, sending node address, target node address, and a sequence number. The magic number is used to identify WAV packets, and allows the packet format to be updated in the future. The quality of service field allows routing decisions to be made based on this value and can be used to route critical management data over a dedicated channel. The time to live value is used to discard misrouted packets while the source transceiver is updated at each hop. This information is used to monitor the health of each transceiver in the network. To identify the packet type, the function code is used. Besides having a regular data packet, the system supports diagnostic packets for fault detection and isolation. The payload length specifies the number of data bytes in the payload, and this supports variable-length packets in the network. The source ADI is the address of the originating interface. This can be used by the destination application to identify the originating source of the packet where the address consists of a subnet, subsystem class within the subnet, a subsystem unit

  14. Packet-Based Protocol Efficiency for Aeronautical and Satellite Communications

    NASA Technical Reports Server (NTRS)

    Carek, David A.

    2005-01-01

    This paper examines the relation between bit error ratios and the effective link efficiency when transporting data with a packet-based protocol. Relations are developed to quantify the impact of a protocol s packet size and header size relative to the bit error ratio of the underlying link. These relations are examined in the context of radio transmissions that exhibit variable error conditions, such as those used in satellite, aeronautical, and other wireless networks. A comparison of two packet sizing methodologies is presented. From these relations, the true ability of a link to deliver user data, or information, is determined. Relations are developed to calculate the optimal protocol packet size forgiven link error characteristics. These relations could be useful in future research for developing an adaptive protocol layer. They can also be used for sizing protocols in the design of static links, where bit error ratios have small variability.
